mesne assignments, to Diamond Power Specialty Corporation, Detroit, Mich., a corporation of Michigan Original application February 15, 1930, Serial No. 428,721, now Patent No. 1,992,336. Divided and this application January 25, 1935, Serial No. 3,478. In Great Britain March 21, 1933 11 Claims.

This invention relates toboiler cleaners and has particular reference to a boiler cleaner of the type which includes means for discharging jets of cleaning fluid adjacent portions of the boiler to be cleaned.

One of the primary objects of this invention is to provide in a boiler cleaner of the above mentioned character, means for prolonging the life of the pipes and conduits which are provided for supplying cleaning fluid to the blower elements of the boiler cleaner. I

Further the invention contemplates the provision of means whereby the cleaning fluid supply conduits and the like will be maintained relatively cool even during periods when cleaning fluid is not passing through the same.

This application is a division of my co -pending application Serial Number 428,721 filed February 15, 1930, which has now issued as Patent No. 1,992,336.

Numerous other objects and advantages of this invention will become moreapparent as the following description proceeds particularly when reference is had to the accompanying drawings wherein Fig. 1 is a semi-diagrammatic elevational view of a portion of a boiler showing my invention applied to the same;

Fig. 2 is a fragmentary side elevational view partly in section of the structure shown in Fig. 1;

Fig. 3 is a sectional view taken substantially on the line 3--3 of Fig. 2;

Fig. 4 is a transverse sectional view through a slightly modified type of construction; and

Fig. 5 is a horizontal sectional view taken substantially on the line 5-5 of Fig. 4. Referring then particularly to the drawings wherein like reference characters designate corresponding parts throughout all views, the numeral I designates generally a boiler having upper and lower headers or drums II and I2 respectively. Connecting the boiler headers in accordance with the usual practice, is a bank l of boiler tubes, the tubes being suitably arranged in rows and the lowermost row or that row nearest the firebox being designated by the reference character IS. The numeral I1 designates a portion of the boiler wall which encloses the boiler drums and tubes. I

For cleaning portions of the boiler, blowerelements are provided, these blower elements being so arranged within the boiler as to discharge cleaning fluid adjacent portions thereof to be cleaned. While these blower elements may be of any desired character, they are diagrammatically relatively cool boiler tubes.

illustrated as crescent shaped members 18 secured as by welding or the like to the boiler tubes I9 of the row l6 of tubes. These crescent shaped members provide cleaning fluid passages 20 with which discharge openings 2| communicate, these openings being arranged so as to discharge cleaning fluid in the desired directions within the boiler.

By integrally uniting the blower element forming members 18 to the boiler tubes I9, it will be understood that the! blower element forming members will be maintained relatively 0001 even during the periods when they are not being supplied with cooling fluid. It is to be understood however, that if desired, the blower elements may be of any desired character, that is either integrally secured to certain boiler tubes as illustrated, or free from connection with the boiler tubes, the present invention being directed more particularly to the means for supplying cleaning fluid to these blower elements or passages.

Referring now more particularly to Figs. 1 and 2, the numeral 25 designates a cleaning fluid supply header which, as illustrated, projects exteriorly of the boiler wall and is preferably provided with a control valve 26. This header extends longitudinally of and lies close adjacent the boiler drum or header 12 with the result that this header is maintained relatively cool by virtue of the cooling influence of the relatively cool drum.

Connecting theheader 25 with the blower elements [8 are branch pipes 21 and by reference to Fig. 2Iof the drawings, it will be noted that these branch pips also lie close adjacent the drum I 2 so as to be cooled by the latter; Additionally, as illustrated in Fig. 3 of the drawings, these branch pipes 21 preferably lie close to the boiler tubes of the bank 15, with the result that besides being maintained cool by virtue of their proximity to the boiler drum, they are also being maintained cool by virtue of their proximity to the The branch supply pipes are shown as being slightly bent as at 28 whereby they may yield slightly to compensate for relative movement between the boiler tubes to which the blower elements are secured and the header incident to differences in expansion and contraction of the header and the boiler tubes.

Asthus far described, it will beapparent that the invention provides blower elements suitably located within a boiler for discharging cleaning fluid adjacent portions of the boiler to be cleaned. ,While these blower elements may be of any desired character, they are preferably integrally united with certain of the boiler tubes of the boiler so that they are maintained relatively cool by these boiler tubes.

The invention further provides a cleaning fluid header which although it is disposed within the boiler is positioned in proximity to andpreferably above the boiler drum or header so that it is not only kept cool by the relatively cool boiler drum but is also shielded by the latter from direct contact with the products of combustion and furnace gases. Connecting the supply header to the blower elements are branch supply pipes which possess a degree of yieldability andwhich also lie close adjacent the boiler drum and also close adjacent the boiler tubes so that these branch supply pipes are likewise maintained relatively cool.

Thus with the construction as thus far described, it will be apparent that the blower elements and the supply pipes and conduits therefor will be protected from destruction by the heat of the furnace even during the intervals when they are not supplied with relatively cool cleaning fluid. Thus the invention provides a construction which may be incorporated in a relatively hot part of the boiler but which will nevertheless possess a relatively prolonged life.

In Figs. 4 and 5, a slightly modified type of construction is disclosed inwhich boiler tubes 35 and 36 are disclosed as communicating with a boiler drum or header 31. Extending longitudinally of the boiler tubes 35 are'blower elements 40 provided with suitable discharge nozzles M for directing jets of cleaning fluid adjacent portions of the boiler to be cleaned.

Extending longitudinally of the boiler tubes 36 are blower elements 45, these elements being likewise provided with suitable discharge nozzles 46. As in the previously described form of construction, the blower elements are preferably crescent shaped members welded or otherwise formed substantially integral with their respective boiler tubes, whereby the blower elements are maintained relatively cool.

In this modified form of construction there is disclosed a cleaning fluid supply header 50 which is disposed wholly within the boiler drum 31 and which is therefore fully protected by the fluid or the vapor in this boiler drum. It .will be understood that at its ends the header'projects exteriorly of the boiler wall and is preferably provided with one or more valves for controllingthe flow of cleaning fluid to and through the header.

Connecting the blower elements 40 to the header 50 are branch pipes 5|, these branch pipes passing through the wall of the boiler drum 3'! and communicating with the blower elements as at 52. It will be noted that even exteriorly of the boiler drum these branch pipes lie close adjacent the boiler drum and their respective boiler tubes and further are shielded from the furnace gases by their respective boiler tubes,

For supplying cleaning fluid from the header 50 to the blower elements 45,.branch pipes 55 are provided, these branch pipes being disposed wholly within the vapor space of the boiler. Thus the branch pipes 55 pass through the boiler'drum and through the tubes 36 communicating with their respectiveblower elements by way of fittings 58 disposed within the'boiler tubes 36. t

In this modified form of construction it will be apparent that the blower elements which are integrally united with the boiler tubes are protected by virtue of their association with the boiler tubes from the extreme heat of the boiler. The'main 2,060,910 "l I! If close adjacent relatively coo-l boiler parts and are further shielded from direct impingement by the furnace gases and products of combustion.

Thus it will be apparent that the invention provides blower elements which preferably are integrally united with relatively cool boiler parts so as to be maintained relatively cool. Additionally, theinvention provides supply pipes and conduits for supplying cleaning fluid to these blower elements, these conduits and the pipes being so arranged that they are also adequately protected from destruction by the heat of the boiler..

For the sake'of convehiencafthe invention has been described'as being embodied in'a cleaner for cleaning boilers. It will beapparent however, that the inventive principles disclosed may be embodied in a device 'for cleaning'k'apparatus similar to boilers and it is to be therefore understood that wherever the word boilers is utilized, it is to be construed as meaning heatexchange apparatus of any character whatever; while the 5 words boiler cleaner are tob'e construed as meaning a cleaner for any such type of apparatus.

While the invention ha s' bleen described with some detail, it is to be understood-that the description is for the purposes of illustration only and is not definitive of the limits of the inventive idea. The right is reserved'to'make such changes in the details of construction and arrangement of parts as will fall within the purview of the attached claims. v p
